You can as it should be a bolt-in but I'd worry if the heat sink would get enough air. You'd have to run the boat without the cowling on.

Cowling?? the top,I was just thinking about cutting a section in it so it would get the air for that and for the power.Also if i do this should i change my prop or will it be alright???

The OS does have more HP and RPM so it should be able to turn a bigger prop.

I would say enough so that you wish you had a surface drive. The boat will probably pick up out of the water when you gun it.

I couldn't give you any speed numbers but it looks like a real powerhouse. Their latest .18 is a real killer though, 42,000 RPM with 20% nitro and using a .12 pipe. This was dyno'ed by a magazine reviewer. The only downside was that the threaded shaft is too short for us boaters to use.

Well, if you do that and a .18 let us know how it runs. You would almost be better off buying a faster boat for what you are going to have in you NH. Gues how I know this. What am I talking about.[] I just bought a Miss Bud with a .18 in it.

EJP, I have one of those motors sitting in my basement in pieces from my sons X-Cellerator. They are fast in his truck but when he had problems with the motor, I tore it down and found the piston falling apart! The skirting is really thin especially at the bottom.

stock stuff always seems to go heywire sumtimes for me[].I was wandering bout the water cooling system whether i would jus put a coupler in the two hoses or to take it out all together.Another thing would this affect the boats stability or not.





btw-does anyone know the rpm range of the stock nitro hammers .15?

i was just thinking could i just put the water cooling head on the .18 since it says in the description of it it is in a .15 crank case although it is a .18. The only other thing i could think of that would stop me from puttin it on other than its size is where the screw hole were drilled and taped.

if the bolt holes do NOT match up , then you might try a KOOL KLAMP , they do work . Or , do as Ron said , make sure the cooling fins get PLENTY of air flow . I popped a buggy engine in a little ABS hull and she rips . ( well , maybe not rips , but does run well )

You can try it , but there doesn't seem to be enough contact ( cooling tubes ) touching the finned area .[&o] Make sure you do the "spit" test after running her a couple of minutes , otherwise , you might not have motor left .[&o]

It is in a miss bud so there is plenty of cooling from the scoop anyway.

well i think i might buy it pretty soone here,I dont know who desinged the stock .15 but they did have the idea of easy starting aftera year of use in mind lol.I have been workin on the engine ALL day[:@] and just got it back together and stil a mother to start.
My conclusion is sell it for bout 35 or 40 or sumtin and buy that os buggy engine within a week or sumtin. or i could buy a .21[>:] what you guys think?

A .21 wouldnt fit the mount and it would be too much for the little boat. I would probaly go with a .18 marine engine myself.
